双钨丝生产工艺中要求分析蓝色氧化钨的氧钨原子比。本方法用14MeV快中子活化氧测定氧/钨原子比。加速器产生的14MeV快中子轰击氧,发生核反应形成的~(16)N放出γ射线能量为6.13和7.13MeV,用3“×3”Nal(Tl)探测器以及相连的多道分析器或单道分析器测量其强度。以纯三氧化钨作标准,并在相同条件下进行活化测量。通过所测量的γ射线的相对
Dual tungsten filament production process requires analysis of tungsten oxide tungsten oxygen atomic ratio. The method uses 14 MeV fast neutron activation oxygen to determine the oxygen / tungsten atomic ratio. The 14MeV neutron bombardment produced by the accelerator bombarded with oxygen and the nuclear reaction of ~ (16) N emitted γ-ray energies of 6.13 and 7.13MeV. The detector was connected with a 3 “x 3” Nal (Tl) detector and a connected multichannel analyzer Or single channel analyzer to measure its intensity. Pure tungsten trioxide as a standard, and under the same conditions for activation measurements. The relative gamma rays passed through
